New details have emerged in the case of Sandra Amezquita's rough arrest last Saturday that was in part captured on video. In the video, an NYPD officer slams Amezquita, who is pregnant, belly-first into the ground. She and her attorney now say cops beat her belly with a baton.

Amezquita provided the photo at left, which shows lacerations on her stomach, to CBS New York. According to Dennis Flores, who filmed her arrest, "they put a Taser to her stomach" in addition to beating her. Yesterday, Amezquita said she experienced vaginal bleeding after the arrest.

The incident occurred after cops tried to arrest Amezquita's son for possession of a knife around 2 a.m. Saturday. When Amezquita and her husband intervened, they both got arrested. "I am afraid of what might happen to my baby," she says.
